MINING IVIACHINE- Application filled March 31, 1924. Serial N'o;703,137.

To all whom it may concern:

Be it known that I, Hnss P. Moronma citizen of the United States, and aresident of Lisbon, in the county of Qolumbi'ana and State of Ohio, haveinvented a new and useful Improvement in Mining Machines, of wh ch thefollowing is a specification.

T his invention relates to mining machines, and particularly to the typeadapted to out kerfs during the mining of, coal or similar materials. d

It is an object of the invention to provide a device which is simple,compact, strong and durable, which is self-contained so as to beconveniently transported from place to place, which can be manufacturedat a reasonable cost, which will not easily get'out of order, and whichwill function etlici'ently for the purpose intended. I

It is a special object to provide a machine of the characterreferred towhich can selectivelydriven by motor or actuated manually, as desired,and in which the nanpower can be conveniently varied according toworking c'onditlons' without changes n the mechanism employed.v I

It is also a special object to provide etfective means both for rotatingtliecutting elements used as well as advancing. such elements bodilyinto the wall formed by the material operated upon, and so associatedthat the mechanism may be set with ease to obtain either result desired.1

Other special objectsare to provide a mining machine equipped with apair of closely spaced cutting disks which are mounted upon a singleintegral hub of novel construction in a unique fashion, in which thecutting disks are of novel form, in which the peripheral teeth for thedisks are not only removable but reversible so as to These and other.objects of the invention.

will more fully appear when taken in conunction with {he followin'descriotion and .l

the

appended claims.

In the accon'ipanying drawings, .Fig. 1 is a side elevational Viewillustrating one en'ibodiment ofthe invention Fig. 2 a verticalsectional View, with parts in elevation, of the machine shown in Fig. 1,Fig. 3 a pla n view of the machine; Fig. 4 afragmen-tary view, partly inelevation and partly in section, showing in detail the construction ofone of the cutting d1sks;-F1g.5adetall elevation of one of thelarger-teeth used on the cutting disk, F ig'. 6 a similar view showingone. of the smaller cutting teeth; Fig. 7 a transverse sectional vlewtaken on the line VIIVII of Fig. 3; Fig. 8 a similar view taken on theline VIIIVIII of -Fig. 3 Fig.

15 an elevation of the parts shown in Fig. 14.

The'frame of the machine comprises the side members 1, 1, the endmembers 2, 2 and the floor or bottom-3, andpreferably the frame is maderectangular in shape;

Surmounting the end member. 2,, and suitably fixed thereto, is. abearing bracket at provided with tlie bearing bosses 5 and 6.

A similar bearing brackett is fixedto the end member 2, and is providedwith corresponding be'aring, bosses 5 and 6.

A driving shaft 7 isjournaled at its opposite ends in the'bossesf)and-5'. and has rigidly attached thereto throughdut its length the gears8, 9 and 10. Tlie criving shaft also carries a bevel pinion 11,,thispinion being formed at the end of a sleeve 12 rctatably journaled inabearing. sleeve 13. The pinion ll and its sleeve 12 is longitudinallyslidable upon the driving shaft, but rotatable therewith, suchconnectionbeing'e'tl'ected bysplining the same upon the shaft, a keyorfeather 14 engaging means of a rotatable shaft,

a groove formed in the driving shaft and extending substantially itsfull extent between the gears 8 and 9.

A short shaft 16 is rotatably mounted in the bearing boss 6 located atthe upper end of the bracket 4t, is equipped with the actuating handles17 and 18 at its opposite ends, and has also fixed thereto the gear 19which meshes with the gear 8 on the driving shaft 7. A similar shaft 16is mounted in the :boss (3, is equipped with the actuating handles 17and 18 at its opposite ends and carries a gear 19 which meshes with thegear 10 on the driving shaft.

The lower edge of the end member 2 of the frame is provided with anelongated opening 20 through which slidingly extends a beam 21, therelative sizes of the opening and the beam assuring a guiding effect forthe beam during its reciprocating or longitudinal sliding movementwithin the frame, the bottom face of the beam preferably lying incontact with the upper face of the floor 3, as clearly shown in Fig. 2of the drawings. The beam 21 comprises two sections, the terminal of thefront section being indicated at 21 while the rear section of the beamis indicated at 21. The rear section 21 is angular in shape, the twolimbs thereof forming preferably a right angle, one limb being connectedto the terminal portion 21 of the front section of the beam by a tongueand groove connection (.Itt Fig. 13), while the upstanding limb of therear section 21 carries rigidly attached thereto the bearii'ig sleeve13. The front and rear sections of the bean: may be adjusted.longitudinally of each other by s3 having one end rotatably mounted in apair of spaced cars 23 ith the polygonal portions 22 be tween the saidears enlarged in cross-section, and having its other end externallythreaded and aging an interiorly threaded opening 21'. .ormed in thebody of the horizontal limb of the rear section of the beam.

Although the coaction between the beam and the opening 20, as well asthe slidable suspension of the pinion 11, which is carried by the rearsection of the beam, effectively support the beam for sliding moven'ientlongitudinally of the frame, in order to positively preclude a tendencyof the beam to 1'0- 30. The pinion 29 meshes with the pinion 11, whilethe sprocket wheel, carried at the lower end of the auxiliary shaft,cooperates with an endless sprocket chain 31 whicli is twined about theintermediate geared portion of an integral hub mounted for rotativemovement in and carried by the free end of the beam 21. This chain ispreferably equipped with a plurality of cleaning lugs 31. 1

Also anchored for rotative movement, but held against longitudinalmovement, within the frame is a screw shaft 33, which engages aninternally threaded boss Set carried at one side of the bearing pedestal2T. Telescopieally engaging the end of the screw shaft anchored in theframe is a sleeve 35 suitably journaled in the end member 2 which hasintegrally formed therewith the gear 36 adapted to mesh with the gear 8on the driving shaft, the sleeve 35 and gear 35 being splined to thescrew shaft so a to be bodily slidable thereon. One end of he sleeve 35is provided with a pair of spaced annular grooves 37, 38, which areadapted to be engaged by a spring pressed pin 39 fixed to the front faceof the end member 2. lVhen the pin 39 engages the groove 3? the sleeve35 is so positioned as to bring the gear 36 into meshing relation withgear 8 while the relative disposition of'these parts when the pin 39engages the groove 33 such that the gear 36 is held in the positionshown by the dotted lines 4.0, in Fig. 2 of the drawings, and out ofmesh with the gear 8. 7

An electric or other suitable driving motor may, if desired, be providedat one end. o the frame, such a motor being indicaod at 41 and itsarmature shaft at ably journaled in the end member 2, and telescopicallyen aging the armature shaft l2 for sliding movement thereupon is asleeve 43 having formed integrallytherewith a gear a l, the sleeve andgear 3--ll corre spend ng in construction to the sleeve and gear and 36,previously described. The gear 4 adapted to be operatively connected ordisconnected, at will, with the ar 10, and locked in these positions bymeal of a spring pressed pin 1-5, corresponding to the pin 39, all asclearly indicated at the right hand side of Fig. 2 of the drawings. Aspreviously noted, the free end of the beam 21 carries a rotatablymounted hi; thereon. This hub comprises but a integral piece having anenlar portion 32, at each side of which is a re duced bearing portion 32and beyond each of the bearing portions is a reduced shouldered terminalas indicated at 32. lhe enlarged central portion around its periphery isequipped with a series of spr eket teeth forming a sprocket gear forcooperation with the sprocket chain 3.. A m in axial bore l6 extendsthrough the body of ltl ing portions 32 of the hub cooperating with theopenings in these plates, and, ifdesired, annular bushings such asshown'at 52 and may be employed. Fixed to the reduced terminal portions32of the hub is .a pair of spaced cutting discs 53., the inner surfacesof which lie in closeproximity to the outer faces of the plates 50, ofthe cutt ng discs is provided with a central aperture fitting over thereduced terminal portion of the hub and having spaced notches formedthereinas indicated at 54, 54-, for receiving the pins 55, 55, fittingwithin thebores 4t? and 17, respectively, and terminating flush'with theends of the hub. A bolt 56 extends completely through the main axialbore 1-6 and serves to bind. a pair of washers 57, 57 into bindingrelation with the ends of the hub for the purpose of holding the partsin assembled relation and for binding the cutting discs 53, 53 intointimate contact with their seats upon the terminal shoulder portions ofthe hub. The

bores 4.9, 19 extend radially of thehub and serve as auxiliaryconducting channels extending from the bore 18 to the bearing surfaces32', providing means forconducting lubricant stored within the bore d8to .;the' said bearings. J

Each of the cutting discs 53, 53 is similarly constructed with theexception of the direction in which the several teeth mounted thereinare projected, and onlyone of these discs need therefore be describednndetail. The disc 53 (see Fig. 4) 1s provided around its periphery with aseries of spaced synr' metrically formed notches or recesses 58, thebottom portion of the notches being substantially semi-circular in shapebut pro rid-ed at the portions adjacent the periphery of the disc withwhat may be termed abut-' ments 59. Lockingly fitting within thesenotches or openings 58 are a seriesof cutting teeth (50 and 61, theteeth 60 being considerably smaller in size than the teeth 61, as

shown in Fig. 4. The base portions 62 ofwhich are adapted to abutagainst the peripheryof the disc as shown at 6 1, and the portions ofthe disc surrounding the opening 58 snugly fitting within the groovewhereby theabutment portions 59 and the shoulder (it serve to lockinglyanchor the teeth against rocking or'pivotal movement with. respect tothe disc, whileat the same The hub is Each @lectively connecting-anddisconnecting time permitting the teeth to be bodily withdrawn radiallyof the disc, and for the purpose of permitting the easy withdrawal ofthe teeth in a radial direction an aperture 65 extends through thethickened vbase of each tooth through which any suitable instrument maybe projected for this purpose.

The detailed construction of both the larger and smaller teeth isclearly shown in Fl 's. 5 and 6' of the drawin s and since theconstruction thereof as far as described is identical, the severalfeatures have been indicated throughout by the same reference numerals.As shown n Figs. 1 and 2, however, the larger teeth 61 on both discs 53and 53 are bent or projected laterally awayv from the space between thediscs, while the smaller teeth 60 on both discs are projected laterallytowards the space between the discs,

and lie in close proximity to the upper and 7 Suitably journaled forrotative movement 7 in a pair of spaced bearings 70, 7 0 carried uponthe side member 1 of the frame is a winding shaft 71 having the windingdrum 72 fixedthereou, and for the purpose of sethe shaft 71 fromthe'gear 9 fixed to the driving shaft 7 isa slidable pinion '53 formedintegrally with a sleere 7st telescopically en the winding shaft and thebearing and corresponding to the construction of the sleeves and gears35, 36 and 43, 14:. Fixed; at the opposite ends of the frame are eyelets75, 75 and 76, T6, and rigidly atached and pro'jectingv from theopposite ends of the frame are the pairs of supporting brackets 77, 77and 78, 787.

tracted position illustrated in Figs. 1 to of the drawings. The beam 21with its eutting head may be advanced by rotating the screw shaft 83,such rotation be ng accom-' plished'by bringing the gear 36 into meshwith the gear 8. 1th the parts thus adusted, power may betransmittedmanually to the shafts 16, 16 andthrough the gearinginterposed between said shafts and the driving shaft 7 to causerotation'of the pinion 11. Aslong. as the gear 36 is in mesh with thegear 8,rotat1on of the shaft 7 will cause rotation of the screw shaft33' which,

due to its cooperation with the internally threaded boss 34 on thepedestal 27, will cause beam 23. to be moved forwardly within the frameso as to bodily advance the en tire cutting head mounted at its free endinto cutting relation with the material to be operated upon. At the sametime, rotation of the gear 11 will through the pinion 29, auxiliaryshaitt 52S. procket wheel 30,

sprocket chain 31, and sprocket gear 32 cause bodily rotation of the huband the cutters mounted thereon.

The series or" larger teeth 61 on the spaced disks 53 and 53, producetwo separated lines of cut, while the series of smaller teeth. thesmaller teeth being preferably interposed between the larger teeth, notonly assist in the cutting action upon the material but due to theirlateral projection within the space between the cutting disks and theirclose proximity to each other effectively remove the entire materialbetween the lines of cut produced by the larger teeth. The brokenn'iaterial accumulating between the disks adjacent the hub is removed bymeans of the lugs 31 tixed to the chain 31, in an obvious fashion.

Due to the provision of the pair of shafts l6, 16, the driving shaft 7may be rotated manually by worlnnen placed at either or both ends ot thetra me, and the man power applied may be varied as desired within thelin'iits provided by the number of handles 17, 18.

In the event that it is desired to operate the shaft 7 by means ot themotor 41, either iinlepeudeutly or simultaneously with the cation oipower by the worknien actuthe shafts 1G, 1%, it is merely neces gear 10.The motor 4-1 is intended for use under unusual conditions, power beinoprimarily applied to the drawing shait by means ot the actuating handlesdescribed.

During the actuation ol the screw shaft the forward bodily movement ofthe beam Si is accompanied by like movement oi? the pedestal 27 and theoperative connections between the pinions 11 and 29, the pinion ll andits sleeve 12 sliding ton wardl on the driving shaft due to its splicedconnection therewith.

tn l igs. lit and 15., the machine is illus traied as mounted foroperation within a. room 80. and in order to suitaliily suspend themachine in working position tor cutting kei'its transversely of theroom, a plurality oi vertical standards 81., 82, 83 and 84 is provided,commonly disposed in the positions illustrated in said figures. Each ofthe standards is provided at its upper end with a screw bolt 83 which isthreaded within the body of the standard so that upon turning movementthereof the same will be projected forcibly against the ceiling of theroom to securely hold the standard in position, the nut 86 beingprovided to hold the parts in locked position. A horizontal beam 8? isattached to the standards 81 and 82 in any suitable manner as by thenotched blocks 88, 88 of well known construction, while a similar beam89 bridges the space between and is likewise attached to the uprightstandarasSS and S4. The beams 87 and 89 may be located at any desirableheight, the position which they assume when a line of cut is desired tobe made adjacent the floor being designated by the showing in Fig. 15,it being understood, however, that the height of th blocks 88, 88 may beadjusted to any desired position for producing the line of cut at thedesired height above the floor oft the room. The frame is bodilysupported upon the beams 87 and 89 by means of the supporting brackets77, 77. and 78, 78 located at the opposite ends of the frame, thesebearing brackets engaging the upper edges of the seams 8? and 89 in themanner clearly shown in Fig. 1d.

The frame, as illustrated in Figs. 1% and 15, is supuorted for cutting alzerf adjacent the door of the room, and for supporting the parts forthis purpose, the lower faces of the brackets 7778 engage the upperedges of the beams 87 and 89. l Vhenever it is desired to cut a kertadjacent the ceiling of the room, it is obvious that the entire machinemay be upturned, with the upper faces of the supporting brackets 77 to78 lying in contact with the upper edges of the beams 5 and S9, in whichposition the bottom or floor 2-3 of the frame will lie adjacent theceiling o't be room.

" a her is to be termed across the en a t the room, it is customary tofirst force the cutting head to the required depth into the material atone side of the room and then bodily move the cutting machinetransversely of the room by sliding the entire machine along the beams87 and 30, thus producing a line of cut thereaeross. ll or the purposeof sliding the frame bodily upon the supporting beams, a cable 90 is p:"l through a pulley or sheave 91 ancl ed as to one side of the room.

One end of the cable is twined about the winding drum 72 while itsopposite end is connected to a ring 93 from which extends a pair oicables 94 and 95, attached respectively to the eyelets 75 and 76', asshown in Fig. ll. lVith the parts thus arranged, winding movement of thedrum will cause the machine to be bodily moved from the left towards theright, as viewed in said figure. Should it be desired to bodily move themachine in the opposite direction, the sheave 91 would be achored at theopposite side of the room, and the cables 94- and 95 attached to theeyelets 75 and 7 6.

As previously pointed out, the construcmounting of the cutting teethupon the disks od of associating the several parts forming the;

entire head. 'In fact, in actual practice," the cutting disks 53 and 53are spaced less than an inch apart, forming a cutting head capable ofproducing comparatively narrow kerfs. i

It is also pointed out that the peculiar 53 and 53 not only provides aconvenient method of removably securmg the teeth in operative position,but due to the symmetrr' cal formation of the openings 58 and the baseportions of the teeth, the teeth maybe reversed so as to functionforeffective cut- 7 ting action regardless of the direction of rotation ofthe cutting diskswitli respect'to the beam on which-they are mounted,

The effective lengthof the beamr'Ql between the hub 32 and the sprocketgear 30:

may be readily varied by means of rotating the shaft 22 wherebyto slidethe rear'portion 21 upon the terminal portion-21f 0f,

the forward section. The shaftHQQ therefore serves as ameans for varyingthe tautness of the chain 31.

The entire machine is constructed of such' proportions that the same maybe readily transported from place to place, and the distance between-thecutting disks is such as to enable it to be effectively used undercrowded circumstances and for the. purpose of securing the removal ofvery thin veins of coal or similar material which would be verydiflicult of access or uneconomical to mine with many of the miningmachines now in use.

While the preferred embodiment of the invention has been illustrated anddescribed, it is apparent that many changes in details of constructionmay be made without departing'from the spirit of the invention, and istherefore not intended to limit the invention beyond the scope"particularly de fined by the appended claims.
